Mini Crawler Hydraulic Excavator SR050 series--
It adopts an advanced hydraulic system with loading sensitive sensor and rotation no tail. It is used to municipal works, gardens building, road maintenance, farmland construction and middle size of construction site.
Main Features--
Rotation without tail to satisfied working in a narrow working site.
• Swing attachment to be able to dig at roadbed or the foot of a wall
•Advanced hydraulic system with loading sensitive sensor to be ensuring an engine power could be used more efficient, it realizes max. digging force and to be possible less fuel.
•Operator’s Cab is designed with air conditioning in order to comfort with longer working time.
•Operation system meets reasonable human-mechanical engineering, which it is effective to reduce operators fatigue at longer working time.
• Maintenance and repairing easier with a button to switch on the cover.
•X model of undercarriage, tilted single side to be more convenience to clean and wash.
